MEALY3UG-S 
While apparently not markedly injurious, a concentration of 
mealybugs ( Phenaccccus cevalliae Ckll.)(Dot. H. liorrison) nn cotton 
in the P oria, Ariz., district is of interest, on account of its 
novelty. Several reports wero received during tho midsummer nonths 
ef snail areas of cotton north of Phoenix having a heavy infestation 
of mealybugs. On- - * of those areas was investigated on August 21. 
The field visited is located about \ nilo north of Peoria. S^voral 
hundred cotton stalks were found to "be heavily infested, some of 
the. terminal twigs "being encrusted several insects deep. The field 
was again visited on September 19, at which tine it was found that 
the number of mealybugs had greatly decreased, with perhaps about 
only 10 percent present, as compared to the numbers observed on the 
occasion of the first visit in August. The field had "been picked 
in the meantime and tho number of "burrs and l»olls on the infested 
stalks showed little appreciable difference from those in the re- 
mainder of the fiold, indicating that little material damage had 
"been inflicted "by tho infestation, (v. P. Cassidy, Bureau of 
Entomology and Plant Quarantine, U. S. D. A.) 
THRIPS 
More reports of damage to cotton "by thrips were received 
during 193^ than for the past several years. The extremely dry 
season, with the resultant poor stands and reduced vitality of 
plants, were contributing factors to the damage caused, as well 
as to tho unusually large thrips population. The most extensive 
damage recurred in the South Atlantic States, although reports of 
serious local injury were received from most of tho Cotton Belt. 
In northeastern Alabama most of the cotton in an entire county 
was practically defoliated during the latter part of June. At 
least 12 species of thrips were collected on cotton, the abundance 
and importance of the different species varying in different sec- 
tions. Frankliniel la fusca (Hinds) was reported from South Caro- 
lina, Alabama, and Mississippi; F. tritici (Fitch) fron South 
Carolina and Mississippi; F. runner i Morg. from Mississippi; F. 
occidontalis Perg. from Arizona; F. gossypii Morg. from Texas; 
Sericothrips variabilis Bach, from South Carolina, Alabama, and 
Mississippi; Thrips tabaci Lind. from South Carolina and Alabama; 
Thrips paniciis Moult, from South Carolina; Hoi jo thrips fesciatus 
Perg. from California; Pr.eudo thrips sp. from Alabama; and Aeolo- 
thrips duvali Moult, from Texas. (U. C. Left in, Buroau of Ento-
